Referring to the drawings the numeral [5 designates generally a housingstructure, which has mounted therein a coin changing mechanism includinga coin delivery means generally designated as it, and an electricallyoperable selector mechanism generally designated as H. The .deliverymechanism i6 comprises a series of outer vertically disposed tubularmagazines l8, I9, 20, 2| and 22. The coins in the magazines [8 to 22inclusive are adapted to gravitatingly move downwardly in the magazinesas the lowermost coins in the magazines are discharged therefrom.

The magazines I 3, l9, and 20 are secured to the top wall 23 of a slidehousing generally designated as 26, and the housing 24 has slidablymounted therein a plurality of horizontally slidable coin delivery slidemembers 25, 26, and 2.7. The slide member 25 is slidable beneath themagazine 18, the slide member 26 is slidable beneath the magazine i9 andthe slide member 21 is slidable beneath the magazine '23. The housing 24is provided with a bottom wall 28 having openings 29, 3t, and 3| thereinwhich overlie a coin delivery chute 32. The coin delivery chute 32 isformed of a downwardly inclined bottom wall 33. A vertical wall 34, andupstanding side Walls 35, and the chute 152 communicates at its lower orforward end with a delivery opening 36 formed in the front wall 37 ofthe housing 15. The housing 2:1 has fixed to the bottom wall 28 thereofa block 38 which is disposed beneath the lower end of the magazine l9.

The space between the upper face of the block 38 and the inner face ofthe top wall 23 of the housing 24 is suflicient to permit a small coinsuch .as a dime to slide between the block 38 and the top wall 23.Theslide I9 is of a thickness sufficient to effect movement of thelowermost coin in the magazine l9, so that this coin will be movedforwardly and will then gravitatingly drop downwardly into the interiorof the housing 23, and downwardly through a delivery opening 38 in thebottom wall 28 which is positioned forwardly of the block 38. The slide21 is of substantial thickness, and in the present instance is of athickness substantially equal to the distance between the top and bottomwalls 23 and 28 respectively, so that five pennies may engage in theopening 43 which is formed in the forward end portion of the slide 21and which is adapted to normally register with the lower open end of themagazine 26. The magazine 20 is adapted to receive pennies, and uponforward movement of the slide 21 the pennies in the recess 40 areadapted to move with the slide 21 and then drop downwardly through adelivery opening 3| formed in the bottom wall 28 forwardly of themagazine 26. The slide 25 is formed with an opening 42 registering withthe lower end of the magazine I8 and the single coin engaging within theopening 42 is adapted to be discharged through an opening 43 formed inthe bottom wall 28 forwardly of the magazine I8.

The magazine I8 is adapted to receive half dollars, and one coin of thisdenomination is moved from beneath the lower end of the magazine l8 andthen discharged into the delivery opening 43 from where the coin dropsinto the delivery chute or hopper 32. A guide or slide housing 44 isdisposed in laterally spaced relation to the housing 24, being thesecond one of the outer pair of delivery housings and is secured to thelower ends of the two magazines, 2| and 22. The housing 44 has slidabletherein a pair of slide members 45 and 46 which are slidable beneath thelower ends of the magazines 2| and 22. The slide members 45 and 46 maybe constructed integral with each other and each slide member 45 and 46is adapted to have an opening therethrough registrable with the lowerends of the magazines 2| and 22 when the slide members are in theirnormal coin receiving position.

The slide members 45 and 46 are similar to the slide members 25, 26, and21 with the exception that the slide member 46 is substantially thickerthan the slide member 45, so that when the slide member 46 is movedforwardly two nickels will be moved out from beneath from the stack ofnickels which are positioned in the magazine 22, for delivery through adelivery opening 6| formed in the housing 44. The magazine 2| is adaptedto receive quarters and the slide 46 is adapted to move only one quarterfrom beneath the stack of coins positioned within the quarter magazine2|, for delivery through a delivery opening 62 in the housing 44. Theouter pair of housings 24 and 44 are associated with each other and theslide members carried thereby are movable as a unit so that when adollar is inserted in the coin controlled slide operating mechanism, theslides in the housings 24 and 44 will deliver coins of severaldenominations making a total of one dollar.

The coin delivery mechanism also includes a second pair of guidehousings 41 and 48 which are disposed inwardly from the housings 24 and44. The housing .41 has secured to the upper side thereof a pair ofupstanding coin magazines 4'9 and 58. The magazine 49 is adapted toreceive dimes, whereas the magazine 56 is adapted to receive pennies.The housing 48 has secured to the upper side thereof a pair ofupstanding magazines 5| and 52. The magazine 5| is adapted to receivenickels, whereas the magazine 52 is adapted to receive quarters. Thehousing 41 has slidable therein a pair of coin delivering slides 53 and54 which may be formed integral with each other and the slide 53 isadapted to deliver one dime into a delivery opening 55 which is formedin the bottom wall of the housing 41. The housing 41 is also providedwith a second delivery opening 56 forwardly of the magazine 56 throughwhich the pennies moved forwardly by the slide 54 are adapted to dropfor delivery to the person inserting the coin in the coin mechanismthrough the delivery chute or hopper 32. The slide 54 is adapted to movefive pennies forwardly from beneath the lower end of the stack of coinsdisposed in the coin magazine 50. The housing 48 has slidable therein apair of integral slide members 51 and 58 and the housing 48 is formedwith a delivery opening 59 forwardly of the magazine 5| through whichtwo nickels are adapted to drop. The housing or guide 48 is also formedwith a second delivery opening 68 forwardly of the magazine 5| throughwhich one quarter is adapted to drop when this one quarter is movedforwardly from beneath the stack of coins in the magazine 52 uponforward movement of the slide 58.

Thehousing 63 has secured to the upper side thereof in upstanding relationcoin magazines 61, 68, and 69. The coin magazine 68 is disposed abovethe slide 65 and the coin magazine 69 is disposed above the slide 66.The slide 64, 65, and 66 may be formed integral with each other, and maybe provided with suitable openings for registry with the lower ends ofthe magazines 61, 68, and 69 respectively, so that when the slides 64,65, and 66 are moved forwardly the coins carried therewith will bedischarged into a delivery opening 10 which is common to all of theslides 64, 65, and 66 and which communicates with the hopper or deliverychute 32. The slide 64 is adapted to move one dime from beneath thestack of dimes in the magazine 69; the slide 65 is adapted to move fivepennies from beneath the stack of pennies in the magazine 68 and theslide 66 is adapted to move two nickels from beneath the stack of coinsin the magazine 60 so that proper change for a quarter will be deliveredfrom the magazines 61, 68, and 69 through the delivery hopper or chute32.

An intermediate pair of slide housings or guides 1| and 12 are disposedbetween the housings 41 and 48 and have secured in upstanding relationthereto coin magazines 13 and 14 respectively. The housing or guide 1|has slidable therein a coin delivery slide 15 for delivering fivepennies from the penny magazine 13 to a delivery opening 16 formed inthe forward lower portion of the housing 1|. The housing 12 has slidabletherein a coin delivering slide 11 which is slidable beneath the lowerend of the magazine 14 for delivering one nickel from the nickelmagazine 14 to a delivery opening 18 formed in the forward portion ofthe housing or guide 12. The delivery openings 16 and 18 communicatewith the hopper or chute 32 for delivering the ejected coins to theperson inserting one dime in the coin slot toibe hereinafter described.

A centrally disposed guide housing 18 is disposed between the twohousings 1| and 12 and forwardly of the housing 53. The housing I9 hassecured in upstanding relation thereto a coin magazine 80 which isadapted to receive pennies for delivery to the delivery chute or hopper32 when a coin delivering slide 8I which is slidable in the housing 19is moved forwardly from beneath the magazine 80. The coins which arefive in number and which are moved forwardly by the slide 8| aredischarged into a delivery opening 82 formed in the forward portion ofthe housing 79 and which communicates with the delivery hopper or chute32.

The coin selector mechanism II includes a vertically disposed coinreceiving chute generally designated as 83 which is substantiallyV-shaped in side elevation and is open at its upper end. The upper endof the chute or coin guide 83 is disposed beneath a hinged closure ordoor 84 carried by the top wall 85 of the housing I5. The closure 84 isprovided with a coin slot 88 communicating with the upper or large endof the chute 83. The lower or small end of the coin receiving chute 83is secured by means of a bracket 81 to a coin receiver 88 mounted on thebottom wall 89 of the housing I5 rearwardly of the coin deliverymechanism It. The guide 83 comprises an inner pair of side walls 90which are of insulated construction and are secured at one edge thereofto a vertical end wall 9! which is also of insulated construction. Ametallic outer housing or jacket encloses the insulated side walls 90and includes a pair of outer side walls 92 and 03 which are connectedtogether by an end wall 94. The end wall 94 is disposed opposite fromthe end wall 9i. The end walls ill and 94 are disposed in downwardlyconvergent relation as shown in Figure 3, the angular relation of thesewalls one to another being such as to effect a wedging and stopping ofcoins of different denominations as these coins move downwardly in theguide 83.

Th end wall 8| adjacent the upper portion thereof is provided with acoin delivery opening 95 which is of sufficient length to permit thedelivery of a dollar therethrough. A contact 96 is disposed in inwardlyprojecting relation with respect to the opening 95, projecting inwardlya slight distance from the inner wall SI for engagement with a dollarwhich is dropped into the chute or guide 83. The contact 96 constitutesa means for limiting the downward movement of a dollar in the guide 83and is carried by a U- shaped supporting member 81. The supportingmember 97 includes a bight portion 98 carried by parallel arms 09 whichare slidable in an opposed pair of upwardly and rearwardly inclinedguide members I and I0! positioned on the opposite sides of the housingor jacket formed by the walls 92, 93, and 94.

The guide structures H30 and HH are formed with guide channels I02 andI03 respectively within which the parallel arms 95 slidably engage. Theguide member 93 is also formed with an opening E04 below the opening 95which is adapted to confront a half dollar. A contact member I05 whichis carried by the bight portion I06 of a U-shaped support is adapted toproject inwardly a slight distance through the opening I04 forengagement with a half dollar and for limiting the downward movement ofthe half dollar within the guide 83.

A contact member III carried by thebight II2 of a U- shaped member I I3 is adapted to project a slightdistance through the opening I I0 for engagement with the edge of aquarter and limit the downward movement of the quarter within the guide83. The U-shaped support II3 includes a pair of parallel arms or legsII4 which are slidable in outwardly opening guide members H5 and H8carried by the side walls 92 and Q3 respectively.

The guide member 83 is formed with a delivery opening II I below theopening IIO which is adapted to confront a nickel disposed in the guide83. A contact member II8 which is carried by the bight portion II9 of aU-shaped member I28 is adapted to project slightly into the guide 83through the opening II 7 thereof for engagement with the edge of anickel and to limit the downward movement of the nickel within the guide83. The parallel arms I 2| of the U-shaped member I20 are slidable inoutwardly opening guides I22 and I23 which are fixed to the side walls92 and 83 respectively and are inclined to the horizontal.

The guides I88, I89, H5, and H8 are also inclined to the horizontal. Alowermost opening 124 is formed in the end wall 0| below the opening illand. is adapted to confront a dime engaging within the lower portion ofthe guide 83. An inwardly projecting stop member I25 may be fixed to thelower end portion of the guide 83 in order to limit the downwardmovement of the smallest coin or dime within the guide 83. A contactmember I28 which is carried by the bight 52'! of a U-shaped support I28is adapted to project slightly into the interior of the guide 83 forengagement with the peripheral edge of a dime to form an electriccontact with the dime and also to limit the downward movement of thedime within the guide 83. The U-shaped support I28 includes a pair ofparallel arms or legs I28 which are slidable in opposed outwardlyopening guide members 530 and I3! which are inclined to the horizontaland are fixed to the side walls 92 and 93. The U-shaped member '91 haspivotally connected to the free ends of the parallel arms 89 thereof, apair of links I32 and. I33.

The link I32 at its forward or lower end is pivotally connected to anarm I3 which is fixed relative to the integral slides 25, 28 and 27. Aguide roll I35 is rotatablycarried by the housing 2t on the inner sidethereof and the arm' I34 engages the roller I 35. The arm I34 is adaptedto move in a horizontal plane whereas the link or connecting member I32moves in an upward and rearward direction.

The link I33 at its lower or forward end is pivotally connected to anarm I35 which is fixed relative to the two integral slides #25 and 40.The

U-shaped member formed by the bight I06 and the parallel arms I0! haspivotally connected to the parallel arms I01 thereof a pair ofdownwardly and forwardly inclined links I3-I and I38. The link I31 atits lower or forward end is 'pivotally connected to an arm I 39 which isfixed relative to the integral slides 53 and 5G and the forward or lowerend of the link I38 is 'pivotally connected to an arm M0 which is fixedrelative to the integral slides 51 and 58. The parallel arms H4 of theU-shaped member I I3 are .piv-

otally connected to a pair of links I II and I42 which at their lowerforward ends are connected to arms I43 and I44 respectively which arefixed relative to the integral slides 64, 65, and 66. The arms I43 andI44 are disposed on opposite sides of the housing 19 as shown in Figurel.

The U-shaped member I has-pivotally connected to the lower ends of theparallel arm I2I thereof, a pair of connecting links I45 and I46. Thelinks I45 and I45 at their lower forward ends are disposed in convergentrelation and are fixed together. The convergent ends of the links I45and I46 are pivotally. connected to a rearwardly extending arm I41 whichis fixed rela tive to the slide SI.

The U-shaped member IE8 has pivotally connected to the parallel legs I29thereof a pair of downwardly and forwardly inclined links or connectingmembers I48 and I49. The lower forward end of the link I48 is pivotallyconnected to a rearwardly extending arm I50 fixed relative to the slide15. The lower forward end of the link I49 is pivotally connected to therear end of an arm I5I which is fixed relative to the slide 11.

In order to provide a means whereby the in serted coins which aredropped into the chute or guide 83 may be ejected from the chute orguide 83, I have provided a coin ejecting and circuit closing structuregenerally designated as I52. The coin ejecting structure I52 includes anupwardly extending contact carrier I53 which is pivotally mounted as atI54 on a bearing structure I55 fixed to the bottom wall 69. The carrierI53 has secured thereto a longitudinally arcuate contact member I56which is movable through an opening I51 formed in the end wall 94. Theinner end of the contact member I56 is disposed in a position forengagement with a dollar and is disposed opposite from the contact 66 sothat when a dollar is inserted in the guide 83, this coin will bridgethe two contacts 96 and I58, and thereby close an electric circuitwithin which these contacts are interposed.

A second longitudinally arcuate contact member I58 is fixed to thecarrier I52 below the contact I56 and is movable through an opening I59formed in the end wall 94 substantially opposite the opening I04 andconfronting the contact I05. When a half dollar is inserted in the guide83 this coin is adapted to bridge the space between the two contacts I05and I58 so as to close the electric circuit to the electric operator forthe carrier I52. The third contact I60 is fixed to the carrier I52 belowthe contact I58 and is movable through an opening I6I formed in the endwall 94 substantially opposite the opening I I0. When a quarter isinserted in the guide 83, this coin is adapted to wedge between the twocontacts III and I 60 so as to thereby bridge the space between thesecontacts and close an electric circuit to the electric operator forswinging or moving the carrier I52. Another longitudinally arcuatecontact I62 is fixed to the carrier I52 and is movable through anopening I63 formed in the end wall 94 substantially opposite the openingI I1. When a nickel is inserted in the guide 83, this coin is adapted towedge between the two contacts H8 and I62 for closing the electriccircuit to the operator for moving the carrier I52. A lowerlongitudinally arcuate contact I64 is fixed to the carrier I52 below thecontact I62 and is movable through an opening I65 formed in the lowerporopening I24 and when a. dime is inserted in the guide 83 this coin isadapted to wedge between the two contacts I26 and I64 for closing anelectric circuit to the operator for the carrier I52.

The upper portion of th carrier I52 is swingable in a substantiallysector shaped housing generally designated as I66 including a pair ofside walls I61 and I68 disposed in parallel relation. The side walls I61are formed adjacent the upper end portion thereof with a longitudinallyarcuate guide I69 within which a roller I10 carried by the carrier I52is adapted to movably engage. The side walls I81 are also formed withlongitudinally arcuate guide channels I1I, I12, I13, and I14 withinwhich rollers I15, I16, I11, and I18 are adapted to movably engage. Thechannels I1I, I12, I13, and I14 are correlated with contact members I58,I60, I62, and I64 respectively.

In order to provide a means whereby the carrier I52 may be rockedrearwardly to a coin ejecting position upon insertion of a coin withinthe guide 83, I have provided an electric motor I19 which is disposedrearwardly of the guide 83. The motor I19 has mounted on the shaft Ithereof a plate I8I having an eccentrically dis.- posed pin I82 mountedtherein. A U-shaped carrier operator I83 has the parallel arms I84thereof disposed on opposite sides of the guide 83 and the housing I66.

The bight I85 of the operator I83 has a rear wardly extending arm I86fixed thereto which is pivotally mounted at its rear end of the crankpin I82. The forward or free ends of the parallel arms I84 of theU-shaped operator I83 are pivotally connected to a pair of oppositelyextending bars I81 which are fixed to the carrier I52 at a point belowthe upper end thereof. In Figure 10 there is disclosed diagrammaticallythe electric circuits associated with the motor I19 and the contactshereinbefore described. These electric circuits include a conductor I88connected to one side of the motor I19 and connected by means ofconductors I89, I90, I9I, I92 and I93 to the contacts 96, I05, III, H8,and I26 respectively. The other side of the motor I19 is connected bymeans of a conductor I94 to the car.- rier I52. In this manner when acoin is inserted in the guide I83 this coin will bridge the correlatedpair of contacts and effect a closing of the electric circuit to themotor I19. When the carrier I52 is moved to its rearmost position thecoin engaging between the engaging contacts will drop down, and theelectric circuit to the motor I19 will thereby be broken.

In order to provide for the continued operation of the motor I19 afterthe coin is released from between a pair of contacts, I have provided astationary resilient contact I95 which is connected by means of aconductor I96 to the conductor I88. The contact I95 is mounted on aplate I91 mounted on the front wall I98 of the coin receiver 88 which ispositioned below the rear contacts 96, I05, III, H8 and I26. A secondresilient contact I99 is fixed to the rear side of the carrier I52 in aposition to engage the stationary resilient contact I95after the carrierI52 has initially started its coin ejecting operation.

The two contacts I95 and I99 are shown more clearly in Figure 11 whereinit will be noted that these contacts are in disengaged position when thecarrier I52 is in its normal forward position so that the electriccircuit to the motor I19 within which the contacts I95 and I99 areinterposed will be broken just prior to the time that the carrier I52reaches its foremost or normal position. By means of the two contactsI95 and I99 the continued operation of the motor H9 is assured so as toprovide for one complete revolution of the crank plate I8I and for thecomplete cycle of the operator I83 which is connected to the carrierI52. In order to provide for a return of the several coin deliveryslides to their normal positions beneath the correlated coin magazineswhen the carrier I52 has returned to its normal forward position, whichis the position shown in Figure 3, I have provided a spring 200 which isconnected at one end to the slide member 25, 26, and 21 and the otherend to the front wall 31 of the housing I5.

The slide members 45 and 40 are also returned to their normal positionbeneath the magazines 2| and 22 by means of a spring 20I fixed at itsrear end to the slide 46, and its forward end to the front wall 31. Theslides 53 and 54 are returned to their normal position beneath themagazines 49 and 50 by means of a spring 202 which is connected to theslide 53 and to the front wall 31. The, slide members 57 and 58 whichare correlated with the slide members 53 and 54 are returned to theirnormal position beneath the magazines and 52 by means of a return spring203 connected at one end to the slide 5'! and the other end to the frontwall 37.

The slides 64, 65, and 66 are returned to their normal positions beneaththe magazines 61, 68, and 69 respectively by means of return springs 204and 205. The slides I5 and II are returned to their normal positionsbeneath the magazines I3 and I4 by means of return springs 206 and 207.The slide 8| is also returned to its normal position beneath themagazine 80 by means of a return spring 203. By means of the slidereturn springs hereinbefore described, the contacts 96, I05, III, H8,and I25 are placed under tension during their rearward and upwardmovement and also promptly returned to their normal positions withrespect to the guide 82 so that when the carrier I52 is in its normalforward position the contacts 93, I05, III, H8 and I26 are also put intheir normal positions.

The coin receiver 88 which is adapted to receive the inserted coinswhich are to be changed, comprises a receptacle formed of side walls209, 2I0, a rear wall 2I I, bottom wall 2I2a and front wall I98. A topwall 2I2 is fixed within the receptacle 88 below the upper end thereofand is formed with an opening 2I3. The opening 2I3 is closed by means ofa pair of doors 2M and 2I5 which are hingedly secured to the top wall 2I2 by means of hinge members 2 I 6, and 2 I I respectively. The doors 2I4 and 2 I 5 are adapted to gravitating- 1y swing downwardly into anopen position 'so as to permit a coin engaging on the upper face thereofto drop into the receiver 80. The doors 2I4 and 2 [5 are resiliently andnormally held in a closed position by means of a pair of pivoted adownwardly bent door engaging cam 2.26 which is adapted to engage theunderside of the door 2I4, when this latter door is in an open position,and the arm or lever 2I8 is moving inwardly to effect closing or raisingof the door 2 I4.

The arm or lever 2I9 is provided with a door closing cam 22'! on itsinner edge thereof and adjacent the forward portion for engagement withthe under side of the door 2I5 so as to facilitate the raising of thedoor 2I5 when the door 2I5 is in an open position. The forward end ofthe arm or lever 2I8 is provided with an integral and obtusely disposedextension 220, and a pivoted arm operating member 229 is pivotallymounted as at 230 on the extension 223, and extends obtusely withrespect to the arm or lever 2| 8.

A spring 23I carried by the extension 228 bears against the outer edgeof the arm or lever operator 229 so as to normally maintain theextension or operator 229 in alignment with the extension 223. The armor lever 259 is formed at its forward end with an obtusely disposedintegral extension 232, and a lever or arm operator 233 is pivotallymounted as at 234 on the extension 232 and is constantly urged to analigning position with respect to the extension 232 by means of a spring235. Ihe two pivoted operators or lever extensions 229 and 233 aredisposed in forwardly convergent relation and are provided at theirforward ends with enlarged heads 23B and 23'! respectively. A V-shapedlever operator 238' is carried by a rearwardly extending support 239which is fixed to the rear side of the carrier I52 and is disposed in aposition for engagement with the head members 236 and 231, so that uponrearward swinging movement of the carrier I52 the levers 2 I0 and 2 I 9will be swung outwardly to a door releasing position. The supportingmemher 239 has fixed thereto a pair of laterally extending pins 240which are adapted to engage and rest upon a supporting track 24Idisposed forwardly of the receptacle 33.

The track 24I is supported in forwardly spaced relation with respect tothe receptacle 88' by means of upwardly and forwardly extendingsupporting braces 242 and 243. The upper end of the guide 83 is fixed tothe lower wall 244 of a depending housing 245 which is disposed belowthe under side of the closure 84. The bottom wall levers or arms 2 I8and 2 I9 respectively which are pivotally mounted at their rear ends onpivot members 220 and 22I respectively.

The pivot members 220 and 2 2I engage through the top wall 2I2. A spring222 mounted on a pin 223 carried by the top wall 2 I2 bears against theforward end and outer edge of the door clos- 244 is provided with a slotor opening 245 registering with the open upper end of the guide 283. Apair of resilient flaps 241 are positioned within the housing 245 andare normally disposed in a horizontal position with their adjacent edgesin substantial contact so as to thereby close the coin slot 85. In orderto provide a means whereby a second coin cannot be inserted in the guide83 while the carrier I52 is moving either rearwardly or forwardly, Ihave provided a guide closing or locking plate 243 which is fixed at oneend to the inner side of the carrier I52 and is slidab-le through anopening 249 formed in the end wall 94. The guide closing or lookingmember 248 is of resilient construction, being normally longitudinallybowed, and is adapted to slide over the surface of the bottom wall 244of the housing 245 for closing the opening of the slot 243.

In the use and operation of this coin changing device the various coinmagazines may be filled with coins by raising the closure 84 which isnor mally locked by means of a locking structure 250. When the magazineshave been filled, the coins positioned therein will engage therespective slide or coin delivery members positioned therebeneath. Inthe event it is desired to change a dollar this coin is inserted in thecoin slot 86 and moved downwardly until the coin engages and wedgesbetween the two contacts 96 and I56. The dollar will engage the contactI56 adjacent the lower portion thereof and will engage the contact I56adjacent the upper portion thereof. As soon as the dollar engagesbetween the two contacts 96 and I56 this inserted coin will close theelectric circuit embodying the conductors I89, I88, and I94 to theelectric motor I19. The motor I19 will thereupon swing the carrier I52rearwardly and as the carrier I52 swings rearwardly the coin will rollwith respect to the two contacts 96 and I56, rolling beneath the contact96 after the coin passes through the opening 9|. The rearward movementof the carrier I52 will pull the yoke or U-shaped member 91 rearwardlyand upwardly, which will effect rearward movement of the links I32 andI33. Rearward and upward movement of the links I32 and I33 will pull theslides 252621 and the slides 45 and 46 respectively rearwardly to a coindelivering position.

Rearward movement of the slides 25, 26, and 21 will effect delivery ofthe coins to the delivery chute or hopper 32 and rearward movement oftheslides 45 and 46 will effect delivery of the coins to the deliverychute or hopper 32. As the slides 25-2 6--21 are moved rear-wardly thespring 208 will be tensioned so that immediately upon dropping of thedollar from between the two contacts 96 and I 56 the spring 288 willreturn the integral slides 25-26--21 to their normal forward positionbeneath the magazines I8 I9 and 20. The same operation is effected bymeans of the spring 20I with respect to the slide 45 and 46. After thedollar or other coin has been delivered down onto the closed doors 2 I4and 2I5 of the receiver 88, the motor I 19 will continue in operation byreason of the closing of the circuit thereto which is effected by thecontacts I95 and I99. The contact I99 is connected by a conductor 25I tothe conductor I94 so that when the contacts I95 and I99 are inengagement with each other a circuit will be closed from the con tactI95 through the conductor I96 and conductor I88 to one side of the motorI19. The other side of the motor I19 is interposed in the closed circuitby means of conductors I94 and 25I, the latter being connected to thecontact I99.

When the carrier I52 initially moves rearwardly to an inserted coinejecting position and a change delivering position, the lever opening orswinging wedge 238 will swing the levers 2 I8 and 2 I9 outwardly to adoorreleasing position thereby permitting the doors 2M and 2I5 togravitatingly swing downwardly to an open position. Thisswingingmovement is provided prior to the dropping of the co n whichcloses the circuit to the motor I19. When the wedge member 238 passesthe heads or forward ends 236 and231 of the pivot members 229 and 233,the levers 2I8 and 2 I9 will be promptly returned to a door closingposition by the springs 222 and 224. At the time the inserted coin dropsdown from between the two contacts 96 and I56, as an example the door2I4 and 2I5 will be in a closed position in view of the fact that atthis time the wedge shaped lever operator 238 will be positionedinwardly of the pivoted arms 229 and 233; the inserted coin which is atthis time effecting operation of the change delivering slides will droponto the closed doors 2I4 and 2I5 and will stay.

plungers, means connecting the other side of said "352- plungers meansconnecting each plunger with a on the upper sides of these doors until asubsequent coin is inserted in the guide 83.

By this means the owner of the change mechanism will be able todetermine the value'of the inserted coin, so that if any coin magazineshould be empty and an insufficient number of coins be delivered to thedelivery chute 32, the owner of the device may promptly make up thedeficiency and may also resupply the empty coin magazine. Thedisposition of the last coin changed on the closed doors 2I4 and 2I5also provides a means whereby the person desiring the change andreceiving the same, cannot dispute the amount of change received.

When the wedge shaped member 238 returns to its forward position uponforward swinging of the carrier I52, the levers 2 I8 and 2I9 will remainin their door locking position by reason of the swinging or pivoting ofthe lever extensions 229 and 230 without movement of the levers 2I8 and2 I9. This is accomplished by providing the springs 23I and 235 ofsubstantially lighter tension that the springs 222 and 224. In thismanner the levers 2I8 and 2I9 are only swung outwardly to a doorreleased position when the wedge shaped operator 238 is moved inwardly.

After the carrier I52 on its return stroke moves forward to a pointwhere the two contacts I and I 99 are in disengaged position, so as tobreak the electric circuit to the motor I19, the carrier I52 continuesforwardly to the end of its movement by means of an adjustable weight252, which is adjustably mounted by means of a set screw 253 on anelongated support 254. The support 254 is disposed at an acute angle tothe length of the carrier I52 and extends forwardly therefrom so as togravitatingly swing the carrier I52 to its foremost or inoperativeposition.
